Hi Alec,
And if we want to send the video to a specific GUI at a specific position?

I mean that I have already constructed a GUI that communicates with a simulink model and changes its parameters. This simulink model is used to implement a DSP algorithm for video compression on DM6437 target and I want inside my GUI to see the input video and the output (compressed) video taken back from the DSP board. How can I take the output of the two Video Display blocks from simulink model? I would appreciate your help very much.

Thanks beforehand,
Alec
